Application filed February 16. 1906'- Serial No. 301.449.

To all whom it may concern:

Be it known that I, JAMEs OAVANAGH, Jr.,

, a citizen of the United States, residing at drawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to lasting machines I and particularly. to thetype of lasting machines employed for working a shoeupper over a lastand securing it in overworked position by repeated operations of the machine applied to different parts of the shoe.

. An example of this type of machine is shown in United States LettersPatent No. 584,744, p

' certain portions of the shoe, such'as the toe,

June 15, 1897, and the present invention is herein shown as embodied ina machine of similar general construction. The machine shown in saidpatent is designed to secure the successively overworked portions of uprtemporarily to the innersole of the shoe y means of tacks which are heldin a raceway and are taken therefrom by a tack separator which deliversthem-to a tack carrier having a tack opening or pocket located near itsfront end. In the operation of the ma-. chine shown in that patent thetack carrier is advanced over the edge of the shoe during each completeoperation of the machine to present the tack held by it in position tobe driven, and a driver is arranged to force the tack from the carrierinto the work when the carrier has reached the limit of its movementover the shoe. Preferably also a presser is provided which is actuatedinwardly over the portion of overworked upper to be secured and, whenworking upon Goodyear or welt shoes, pressesthe upper down upon themarginal portion orfeather-edge of the innersole and also, as itadvances, presses the upper materials inwardly against the shoulder orlip with which the innersole of'a welt shoe is'provided. The presserthus acts to force the upper' materials into the angle of union betweenthe lip and feather-edge of-the innersole', in which plosition it issubsequently secured by stitc 'ng which passes through the lip of theinnersole, the over- -worked upper material, and a superposed welt,as-is well understood. \The presser above'described may be mounted andactuated in any suitable way, but as herein shown itis attached to thelowerface of the tack carrier and is advanced and retracted with saidcarrier. It is desirable that the tack contained in the carrier, whichis tobe driven through the upper material and into. the innersole, beinserted at the angle of union between the feather-edge and the lip ofthe innersole in order that it may hold the upper material in properposition until it is permanently attached to the lip in a subsequentoperation. In order that the tack contained in the pocket of the carriermay be drivenin said angle of union, the end of the tack car ier isnecessarily somewhat in ad-. vance of the presser. The end face of thecarrier consequently presses the upper slightly over the lip of theinnersole when the carrier is in its most advanced position. In lastingwhich require to be plaited for taking care of the fullness of the uppermaterials,apresser is employed which is shown in the accompanyingdrawings as a thin plate and will herein be sometimes referred to as.the thin ipresser to distinguish it from the presser, rst described,which is relatively thick and will be sometimes herein. designated asthe thick presser It is the general practice at the present time toemploy wire for binding the upper in overworked position on the toe ofwelt shoes instead of drivin tacks for that urpose. The machine of saidLetters Patent has been equipped with means for presenting wire to beused for binding. the upper, one form of.

such wire-presenting means being shown in United States Letters PatentNo. 696,740, granted April 1 1902. in the latter Letters Patent by whichthe delivery of tacks may be suspended while wire is being used. In theuse of the machine thus equipped the wire, which is held under tension,is secured to a tack at one side of the shoe and drawn about the toe ofthe shoe asthe lastin proceeds to bind in overworked. position/thesuccessively lasted portions of upper material and, finally, is securedto a tack at the opposite sideof the. shoe. The thin presser abovementioned is employed for pressing the upper material firmly into theangle of union between the lip and feather-edge of the innersole andforms a seatfor the wire in the angle between the portion of upper whichlies over'and is parallel with Means is also shown Q 40 cause the thinacting end of the thin presser seat and hasno tendency to ride up overthe lip into aposition which would permit the overworked upper to slipback and slackenp The fullness o the upper material at the toe 1'oausesits Tee-edge to tend to wardly toward-the edge of the si oe,thereby increasing the security with which the wire "is seated in itsholding position.

.It is-found in, practice that thereciprocat- 1- pack 'carrier, which inits tack delivering position extends slightly beyond the outer ,faceofthe lip of the innersole,.bends the upstanding edge portionof uppermaterial in wardly over thehp and, therefore, tends to lift or str'ai'htenup the portion which-has been pressed-into the angle of unionbetween the lip and feather-edge. This action on the upper displaces thewire slightlyfrom its seat an permits the overworked upper material toslip back so that the toe of the shoe is not 25, as tightly lasted as itshould be. In view of this difficulty, and the fact that the tackcarrier is not needed while that portion of the shoe is being lastedwhich is, secured by wire insteadof, tacks, means is provided inaccordance with one feature of this invention for discontinuing themovement of the tack carrier into-position to engage the upstand ingflangeol upper material. In the embodiment of the invention herein shownthe movement of the tack carrier is entirely suspended by means undercontrol of the opera tor. The thick presser, being mounted on theearrier, of course has its movement discontinued when the operation ofthe tack car nor is suspended. This is advantageous beforms a betterseat for the wire when it alone forces" the upper material into theangle of union between the lip and feather-edgeof the inner-solethanwhen the blunt-ended thick presser also acts upon the uppermaterial. 'lhethick resser, however, is more effective than the t .inpresser in lasting the sides of the shoe and particularly inlasting theheel portion of the shoe, in which the stock to be pressed over the ed eof the last is bulky and usually stiff. It wi I now be understood thatthe thin presser is needed While the portion of the shoe is being lastedwhich is secured by wire and that the thick resser. and tack carrier areneeded While t ose portions of the shoe are being lasted which arefastened by tacks] Another feature of the invention,

therefore? consists, providing means renderingsone of said pressersinoperative when the other ip'res'ser is operative; Each presser is.herein shown as detachably con nected with a source of power by which itis operated and meansis prov1ded fOr-simulta neously disconnecting one.presser from its roject out "tack carrier, the thick presser, and thedriver creme operating means when the other. presser is connected to itsoperating means so'that the change from one presser to the other is madeby a single act of the operator Arrincidental advant'agewhich resultsfromm'c'ving the tack carrier into its retracted position is that it isthereby located Where it does not interfere with the operation of anyother parts of the machine. In the normal operation of the machine thetack carrier advances before the grippers of the overworking mechanismrelease the upper and when lastin the inelastic stock which isfrequently foun at the toe of the shoe where the upper materialincludes, the toe stitlenings it frequently happens that. the grippers,which are yieldingly actuated, occu y a position near enough to the edgeof I the s oe to be struckand marred bytheQadvancing tack carrier. v j rIn the machine herein shown as embodying 8,5 the invention the tackseparator is arranged to be actuated by mechanism including apart.carried by the tack carrier andit of'oourse follows that the movementsof the tack sepa rator are stopped and the delivery of'tacks to the tackcarrier isdiscontin'ued when the-4; movement of the tack carrieris-suspended. 'A further feature of the invention consists in providingmeans by which a normally op-' erative tack driver may berenderedinopera- 9o t ve while the machine continues in operatlQIl for lfastmgportions otthe shoe in which it is not desired to have tacks inserted-bythedriver. It will be obvious that the driveris not needed while wire isbeing used instead of tacks for securing the upper in overworkedposition, and inasmuch as its actuation causes some noise and also wear,as well as vibration of the machine it is advantageous to render thedriver inopera'tivewhen. tacks are not to'be driven. in the machineherein shown the driver is actuated by a cam which raises it against thetension of a spring that imparts to the-driver its downward stroke; Asillustrated, means is providedun'der control of the operator forsecuring the driver in its raised position while portions of'the shoeare beinglasted which are to be secured by other means than tacks andfor-releasing the driver again when tacks are .tobe driven.

Preferably the ineansifor rendering thedriver operative or inoperativeis connected with the means for controlling the operation eithe 7 tackcarrier and the presser so that the open ator may by a singleadjustmentirender the inoperative and. the thin presser operative Whenit is desir" to last a portion of the shoe which is to heag'ea-u gdlbwire and Tandems said driver, tack: i- 2; and thickpressef "operativeand that-hm presS9piin p ti t when-the portion of'the shoe to be securedby-' tacks is about 'tob'e lasted.

h'leohanism 1s provided"inthe machinefor imparting to the grippersappropriate move- 'l3o ments for causing them to plait the appear whenthe toe of the shoe is being lasted, and as herein shown, this mechanismis connected. with the controlling mechanism above mentioned so that itis thrown into operation when. the thin 'presser is operative and isthrown out of operation when the thin presser is inoperative. j i

In lasting the heel of the shoe the grippers are not employed becausethe uf iler is not so supported at the heel portion 0 t e last that itwould be stretched if it were pulled by the .grippers, and all that isrequired of the machine is for it to conform the upper material closelyto the contour of the sides of the last and to bend it over and secureit to the innersole on the bottom of the last. For these purposes theshoe is pressed laterally against an edge rest having a face ofsufiiciently vertical width to present a substantial bearing for theside of the shoe and the upper mate- .rial is bent over the edge of thelast and pressed into position by the reciprocating thick presserheretofore mentioned. The. fullness of up er material bent over theconvex edge of t 1e last forms crimps-or puckers which it is desirableshould be pressed as smooth and flat as ossible. It is found in practicethat in lasting the heel of a shoe the upper material stands away fromthe last more or less at the side of the path of-the tack carrier towardwhich the lasting proceeds and that the reciprocating presser does not,for this reason, work the upstanding edge of the material directlyinwards as it should do. As a result the upper is sometimes notconformed accurately to the sides of the last at the heel and sometimesan extra fullness of upper material accumulates on the side toward whichthe lasting proceeds. It is also found that the crimps or puckers areformed. between the path followed by the pr'esser in one advance and thepath followed by it in its next advance, or between two adjacent tacks.The crimps formed in this position are not iessed down as smoothly asthey are -when t ey are located in the path of the presser-as, forexample, near the tacks. In view of these conditions I have provided animproved work gage or edge rest which is'so formed that it can conformthe upper to the contour of a curved side of the last. As herein shownthe edge rest is constructed to conform the upper to contour of the sideof Lhe last whether more. or less convex or concave, as well 61:5 to astraight surface, and it serves to hold the upper snugly against thelast at the point adjacent to the advance side of the presser where ithas heretofore had a tendency to stand away-from the side of the last.The edge rest thus positions the upstanding edge of upper material inconformity with the contour of the side of the last and where itwillbe'bont squarely over the 65 edge of'the last by the reciprocatingpresser.

PAS shown, the edge rest is provided with a flexible work-engaging headto enable it to adapt itself to the contour of the" side of the last.The head of the edge rest may conveniently consist, as illustrated, oftwo face plates arranged edge to edge and pivotally connected to asupport at opposite sides of the line of separation between them. .This

construction enables the platesto turn indendently in conforming to thecontour of the work. The pivotal connections between the plates andsupports are shown as located near the outer sides of the path of thepresser and thcrefore'the rest presents a rigid bearin to the side ofthe shoe at these two points. when the upper is thus held by the restthe reciprocating lpres'ser forces it into desired position and t ecrimps or uckers are usually formed adjacent to w ere the tack is drivenand are l-aidvery smoothly by the presser. I

Another advantage of the improved edge gage is that thepivotalconnection'of the face plates to the support. at pointsspacedapart enables theadjacent edge of the plates to re cede or yield whenthe work is presented in These and other features of the invention,

including certain details of construction and combinations of parts,will hereinafter be more fully described and pointed out inthe claims.

reason oi its form and its greater strength for pressing theuppermaterials into lasted po. sition at the sides and especially at the heellit isalso found that the move Inentof the tack carrier intoits advancedposition when the upper material is bein se' curedbywire is attended bycertain dlsadk vantages. The most important disadvam.

e is that the tack carrier advances as hereta to ore explained toaosition irnwhich its ifeatherrcdge and lip I unseat the wire so tnfront edge contacts wit the u standing upper material on the outer side0 the lip of the mnersole and oends the upper materlal over the lip.This bonding of the up or material tends to pull it out of theanglelie-tween. the of the innersoie and'fto at the wire holds the up per,less securely and sometimes permits it to slip-back towardthe edge'ofthe last so that the shoe is not lastedastightly as it should be.Another disadvantage incident to the continued movement of the tackcarrier and,

thick presser at times when they are not needed is that useless wear ofthe moving parts is occasioned thereby. In accordance with anotherfeature of this invention means is provided for preventingth'e tactcarrier from advancing into a position where it'tends to displace theoverworked upper materials,

and, as herein shown, this means consists-in mechanism for disconnectingthe tack carrier and thick presser from their driving mechanism. Whilethis may be accomphshed in various ways, the machine herein illustrateds provided with means for disconnecting the cam 88 from the drivingshaft D. The cam 88 is shown as loose on the driving shaft and 1n theconstruction illustrated'ln F1gs. 2 and 11 is provided with, a deviceshown" oted, spring-pressed latch- 10*adapted to en;

When the latch is seated in the notch ofsaid collar the cam 88 isrotated. with the shaft andthe tack carrier and thick presser arereciproca'ted, as has been described. For the purpose of disconnectingthe cam from the driving. shaft means is provided for withdrawing thelatch from the notch in the collar 12 and preferahly for arrestingthecam 88Jat apoint in its r rotation atwhlch the tack carrier and thickpresses occupy their retracted positions.

In themachine shown a. latch 21 is arranged to engage the driver bar and holdthe latter at substantially the limit ofthe upward movement imparted toitby the cam 91.- The driver bar is shown-as provided with a notch 22hich receives an inwardly projecting end of the latch 21. The latch isshown as mountedlooselyg on a shaft 24 and acted upon by a spring 27 forswinging it in the direction to engage. the notch-on t e driver bar.

. The rockshaft 24 is provided with a fixed collar'28'having'a shoulderto en a c with a stud-29 on the latch. The roc has a second" collar 30having an arm to which is pivotally connected a link 31 ere tending toan arm32 on the vertical rock shaft 71} The arm 32'is'secu1'ed to therock-'- shaft-in such angular relation to the devices for-disconnect"thetack carrier, the tack separator,-and t .e'thic kpresser from'theirdriving mechanism andthe devices for controlling the movementof the thinpresser and the plaiting mechanism that the latch is heldout, ofposition for engagin the driver when the-tack block and the teeseparator I are operative 'for presenting tacks to be Q0 gri'ven; Theposition of the arm 32 on the ockshaft 71 is such as to permit the latch21 Y to engage the driver and render it inoperative when the tackcarrier and tack separator are rendered inoperative. It is to be noted.65 that the latch 21 isyieldingly actuated into aft also position toengage the driver so that it presents no obstacle to the movement of therockshaft 71 at any point in the cycle of operations of the machine. Itwill also be 0 served that the device 14 may be moved at any time duringthe cycle of operations of the machine into position to cooperate withedges to the front end of the arm v10.;eigThe I plates each have alimited amount of free movement about their ivots, their movement in onedirection be ng limited by contact of their adjacent ends with the endof the arm 10 and their movemcntfin the opposite direction bein limitedby sto s 46.

This construction 0' the edge rest ena les it to present an approximatey uniform hearing against convex, cpficave, or straight portions of theside of a ast and is particularly useful whenlasting the heel of a shoewhere the upper requires to be conformed by the edge rest to the convexcontour of the side of the last. The edge rest constructed as shownpresses the upper against the side of the last at the advance side ofthe path of the reci rocating resser where it normally ten s to standack from the last. The rest thus holds the upper inproper position to beacted upon b the presser and forced squarely inward and "Killed orcrimped. The pivotal connections of the plates 41 to the supporting armat points spaced a art as shown insure the presentation an pressure ofthe shoe always against the central portion of th -gage and therefore inredetermined relation to the gage and to t 1e working parts of themachine.

in the operation oi the machine, the heel and sides of the shoe will belasted in the usual manner, the shoe being held in the hands of theoperator or supported by a jack if desired and pressed against the edgerest, the acting face of which will ada t'itself to the contour of thedifferent portions of the shoe presented to it. After. the upper hasbeen worked over the last and secured by tacks to the innersole'on thesides and heel,

tacks will be inserted artiallyinto the shoe bottom at o osite si es ofthe toe, and the machine wil tor to secure the en of the binding wire toone of the tacks. Before re-starting themachine the-operator will shiftthe knee lever to turn the rockshaft 71 in the direction to disconnectthe cam 88 from the actuating shaft 1), to permit the latch 21 to engagethe driver e stop ed to permit the operamovements to the grippers.

bar 90, to move the cam plate 23 for'forcing the thin presser into itsoperative position andtoput the plunger 42 into positionto actuate saidthin presser, and also to render operative the mechanism fo'r givingplaiting All these adjustments having been effected by a single movementof the rockshaft, as before explained, the machineis restarted andthereafter the successively overworked portions of upper material areforced into the angle of union between the lip and feather-edge of theinnersole by the thin presser and are bound in lasted position about thetoe ofthe shoe by the wire w. When the lasting of the toe is completedthe machine will be sto ped and the wire will be secured to the tacli onthe side where the lasting operation is ended. The knee lever will thenbe shifted. to turn the rockshait 71 in the direction for restoringadjusted by i t, and the machine is" then ready for lasting the sidesand heel of another'shoe. t5 Having explained the nature of theinvention and described a construction embodying it in one of the bestforms now known to' me,
